Anthropic brings Claude Fable 5 to the public — with guardrails doing much of the work
Anthropic has announced Claude Fable 5 as a public-facing version of its Mythos-class model, paired with a safety design that routes some higher-risk requests elsewhere. The release matters not just because of the model claims, but because it shows where frontier AI deployment is heading: broader access, narrower permissions, and far more explicit controls.
As announced at the closing, everyone will be able to choose a preferred topic for themselves, and will be able to upgrade their ticket with additional topics for prices that will be smaller than upgrades that were between different summits this year. Plus, until now we couldn't have cross-summit topics, such as "security", and attendees who wanted just security sessions effectively had to buy tickets for all three summits. Now that will not be the case any more. All tickets pass is still there.
Still unclear: so chosing between ECS Passes with (585) or without tutorial day (Temp 325) and ECS All Sessions (565) or Master Pass (745), still defines if you can follow all sessions or not, but there will be an upgrade later on that would be smaller than the difference between the current prices that would allow you to follow all sessions as well?
